Title: Improvements relating to Semiconductor Protective Device
IPC: H02H9/02
Filed: 1968-02-15
Abstract: 1,179,518. Semi-conductor devices. LIGNES TELEGRAPHIQUES ET TELEPHONIQUES. 15 Feb., 1968 [24 March, 1967], No. 7551/68. Heading H1K. A device which operates as a current regulator and as a cut-out protection against current surges comprises, in a closed casing, a fuse wire- 7 in series with a semi-conductor body 1. The body 1 is doped such that at the normal operating current it exhibits a positive temperature coefficient of resistivity, while at the limiting current at which the fuse wire 7 burns out the coefficient is negative, the resistivity being higher at the operating current than at the limiting current. In the region of the operating current the positive coefficient provides current regulation, whereas at higher currents the negative coefficient induces a rapid increase of current to the limiting value, thereby ensuring a short delay time prior to burning-out of the fuse 7. The semi-conductor 1 may be of Si doped with B or P, or of P-type GaAs. The fuse wire 7 may be of Au, while the terminal plates 2, 3 and header 6 may be of Au-plated Ni/Fe alloy. In another configuration one end of the semi-conductor body 1 is mounted directly on the header 6. An intermediate output lead 4 may be provided to enable an alarm device to be connected in parallel with the fuse wire 7.
